!htrace is an awesome extension, easily one of my favorites.

I recall debugging a registry handle leak in third-party code and a desktop handle leak in in-house code, among other things, using this great tool.

A great example of the added value of dbgeng extensions given to Windbg over alternative debuggers such Ollydbg, Visual Studio, etc.

I think that in a more general sense, some great capabilities of App Verifier are unknown to the developer community at large and should be evangelized more.

Hopefully options providing finer granularity will be added to the !htrace extension command in future DTW releases, allowing filtering handles based on their type and filtering stack traces based on the contents, !findstack style, and so on.

doesn't work in Internet Explorer, even though I have the MSDN library installed.
